Random Amplified Polymorphic Dna Markers In Sweetpotato Infected With Fusarium Lateritium, Frank A. Buffone, Don R. La Bonte, Christopher A. Clark Jan 1996

Random Amplified Polymorphic Dna Markers In Sweetpotato Infected With Fusarium Lateritium, Frank A. Buffone, Don R. La Bonte, Christopher A. Clark

Faculty Publications

DNA isolated from Fusarium lateritium Nees: Fr.-infected 'Jewel' sweetpotato [Ipomoea batatas (L.) Lam.] plants was compared to F. lateritium-free 'Jewel' plants for differences in random amplified polymorphic DNA (RAPD) marker products. Differences in RAPD marker products were detected. Amplified DNA isolations from F. lateritium-infected 'Jewel' plants generated additional, unique DNA fragments not found in amplified DNA isolations of F. lateritium-free 'Jewel' plants. These unique amplified DNA fragments were consistent with those obtained from amplified DNA isolations of the F. lateritium isolate, 91-27-2, used for inoculation. We found that F. lateritium DNA successfully competes with sweetpotato DNA in the polymerase chain …

Heritability Estimates For Reaction Resistance To Sweetpotato Chlorotic Leaf Distortion Caused By Fusarium Lateritium, Bong Kyoo Kim, Don R. La Bonte, Christopher A. Clark, Mario I. Buteler Jan 1996

Heritability Estimates For Reaction Resistance To Sweetpotato Chlorotic Leaf Distortion Caused By Fusarium Lateritium, Bong Kyoo Kim, Don R. La Bonte, Christopher A. Clark, Mario I. Buteler

Faculty Publications

Narrow-sense heritabilities for reaction to chlorotic leaf distortion (CLD), incited by Fusarium lateritium Nees: Fr., were estimated in sweetpotato [Ipomoea batatas (L.) Lam] by variance component analysis and parent-offspring regression. Visually rated severity reactions to CLD varied greatly among the 20 parents used to generate half-sib progeny from open- pollinated nurseries in 1990 and 1991. Progeny from each nursery were evaluated along with parents in a completely randomized design in two consecutive years. Narrow-sense heritability (h2) estimates based on variance components were moderate on an entry mean basis at 0.61 in 1990, 0.38 in 1991, and 0.33 for the two …

Obesity And Hypertension Prevalence In Populations Of African Origin, Jay S. Kaufman, Ramón A. Durazo-Arvizu, Charles N. Rotimi, Daniel L. Mcgee, Richard S. Cooper Jan 1996

Obesity And Hypertension Prevalence In Populations Of African Origin, Jay S. Kaufman, Ramón A. Durazo-Arvizu, Charles N. Rotimi, Daniel L. Mcgee, Richard S. Cooper

Faculty Publications

Obesity has been shown to be associated with hypertension in Africa, the Caribbean, and the United States, but there has not previously been an opportunity to compare the magnitude of this relation and estimate the contribution of obesity to hypertension risk across these populations. The International Collaborative Study on Hypertension in Blacks (ICSHIB) used age-stratified sampling and a standardized protocol to measure blood pressure and hypertension risk factors. We analyzed data on 9,102 men and women, age 25-74 years, from seven sites. We studied hypertension (140/90 mmHg or medication) in relation to body mass index (BMI) and sex-specific BMI cutpoints …

Relationship Between Birth Weight And Awake Blood Pressure In Children And Adolescents In Absence Of Intrauterine Growth Retardation, Empar Lurbe, Josep Redon, Vicente Alvarez, Ramon Durazo, Ana Gomez, Jose Tacons, Richard S. Cooper Jan 1996

Relationship Between Birth Weight And Awake Blood Pressure In Children And Adolescents In Absence Of Intrauterine Growth Retardation, Empar Lurbe, Josep Redon, Vicente Alvarez, Ramon Durazo, Ana Gomez, Jose Tacons, Richard S. Cooper

Faculty Publications

This study was designed to examine the relationship between birth weight (BW) and ambulatory blood pressure in children and adolescents, born at term in absence of intrauterine growth retardation. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed on 332 children (150 boys), aged from 6 to 16 years. Subjects were stratified by BW tertiles and age. ABPM was performed using SpaceLabs 90207 monitor during a regular school day. Blood pressure (BP) was measured every 20 min from 06:00 to 24:00, and thereafter every 30 min. Means of systolic BP (SBP) and diastolic BP (DBP) during 24 h, daytime (08:00 …

Gravimetric Method For The Measurement Of Sugar Consumption By Adult Velvetbean Caterpillar (Lepidoptera: Noctuidae), Xikui Wei, Seth J. Johnson Jan 1996

Gravimetric Method For The Measurement Of Sugar Consumption By Adult Velvetbean Caterpillar (Lepidoptera: Noctuidae), Xikui Wei, Seth J. Johnson

Faculty Publications

Determination of food consumption by adult Lepidoptera, especially noctuid species, has not been well studied, possibly because of a lack of appropriate methodology. In order to measure sugar consumption by velvetbean caterpillar, Anticarsia gemmatalis Hubner, a gravimetric method was developed and is presented here together with results obtained using this method. After 24-h exposure to a moth, liquid consumption by the moth was determined by weighing the remaining solution on an electronic balance. The amount of solution consumed was calculated by converting the difference between the weight of the remaining solution and that of the unfed control to a volumetric …

Beet Armyworm (Lepidoptera: Noctuidae) Control On Cotton In Louisiana, V. J. Mascarenhas, B. R. Leonard, E. Burris, J. B. Graves Jan 1996

Beet Armyworm (Lepidoptera: Noctuidae) Control On Cotton In Louisiana, V. J. Mascarenhas, B. R. Leonard, E. Burris, J. B. Graves

Faculty Publications

Efficacy of selected labeled and experimental insecticides against beet armyworm, Spodoptera exigua (Hubner), populations from Louisiana were determined in both a laboratory diet bioassay and in replicated field plots. Significantly higher LC50'S for chlorpyrifos and thiodicarb were observed for one of two field-collected strains relative to a laboratory-reference strain in the laboratory diet bioassays. No significant differences in susceptibility between the reference strain and field-collected strains were observed for chlorfenapyr (proposed common name), spinosad or tebufenozide. For the reference strain, LC50's (ppm) for tebufenozide, spinosad, chlorfenapyr, chlorpyrifos, and thiodicarb were 2.6, 2.8, 4.8, 4.9, and 319.8, respectively. In two field …

Strategic Agricultural Trade Policy Interdependence And The Exchange Rate: A Game Theoretic Analysis, P. Lynn Kennedy Jan 1996

Strategic Agricultural Trade Policy Interdependence And The Exchange Rate: A Game Theoretic Analysis, P. Lynn Kennedy

Faculty Publications

Strategic Agricultural Trade Policy Interdependence is modeled using a game theoretic framework. The model distinguishes between the European Community, the United States and a politically passive rest-of-the-world. Particular emphasis is placed on the effect of the exchange rate on the equilibrium outcome of this game. Without compensatory payments to those with the highest political influence, the results suggest that only modest reform is possible. With compensation, liberalization occurs but free trade is not obtained. Simulations also indicate that the U.S. gains incentive to reduce protection given a depreciation of the dollar, while incentive to liberalize trade policies decreases as the …

We show that, for every integer n greater than two, there is a number N such that every 3-connected binary matroid with at least N elements has a minor that is isomorphic to the cycle matroid of K3,n, its dual, the cycle matroid of the wheel with n spokes, or the vector matroid of the binary matrix (In|Jn-In), where Jn is the n × n matrix of all ones. © 1996 Academic Press, Inc.

Excluding A Long Double Path Minor, Guoli Ding Jan 1996

Excluding A Long Double Path Minor, Guoli Ding

Faculty Publications

The "height" of a graph G is defined to be the number of steps to construct G by two simple graph operations. Let Bn be the graph obtained from an n-edge path by doubling each edge in parallel. Then, for any minor-closed class script G of graphs, the following are proved to be equivalent: (1) Some Bn is not in script G; (2) There is a number h such that every graph in script G has height at most h; (3) script G is well-quasi-ordered by the topological minor relation; (4) There is a polynomial function p( • ) such …

Composites With Imperfect Interface, Robert Lipton, Bog D.An Vernescu Jan 1996

Composites With Imperfect Interface, Robert Lipton, Bog D.An Vernescu

Faculty Publications

New variational principles and bounds are introduced, describing the effective conductivity tensor for anisotropic two-phase heat conducting composites with interfacial surface resistance between phases. The new upper bound is given in terms of the two-point correlation function, component volume fractions and moment of inertia tensor for the surface of each heterogeneity. The new lower bound is given in terms of the interfacial surface area, component volume fractions and a scale-free matrix of parameters. This matrix corresponds to the effective conductivity associated with the same geometry but with non-conducting inclusions. The bounds are applied to theoretically predict the occurrence of size …

On Inequivalent Representations Of Matroids Over Finite Fields, James Oxley, Dirk Vertigan, Geoff Whittle Jan 1996

On Inequivalent Representations Of Matroids Over Finite Fields, James Oxley, Dirk Vertigan, Geoff Whittle

Faculty Publications

Kahn conjectured in 1988 that, for each prime power q, there is an integer n(q) such that no 3-connected GF(q)-representable matroid has more than n(q) inequivalent GF(q)-representations. At the time, this conjecture was known to be true for q = 2 and q = 3, and Kahn had just proved it for q = 4. In this paper, we prove the conjecture for q = 5, showing that 6 is a sharp value for n(5). Moreover, we also show that the conjecture is false for all larger values of q. © 1996 Academic Press, Inc.

Extension Sets For Real Analytic Functions And Applications To Radon Transforms, Vernor Arguedas, Ricardo Estrada Jan 1996

Extension Sets For Real Analytic Functions And Applications To Radon Transforms, Vernor Arguedas, Ricardo Estrada

Faculty Publications

The real analytic character of a function f(x,y) is determined from its behavior along radial directions fθ(s) = f(s cos θ, s sin θ) for θ ∈ E, where Ε is a "small" set A support theorem for Radon transforms in the plane is proved In particular if fθ extends to an entire function for θ ∈ Ε and ƒ (x, y) is real analytic in R2 then it also extends to an entire function in C2. © 1996, Hindawi Publishing Corporation.

Multigrid Methods For Parameter Dependent Problems, Susanne C. Brenner Jan 1996

Multigrid Methods For Parameter Dependent Problems, Susanne C. Brenner

Faculty Publications

Multigrid methods for parameter dependent problems are discussed. The contraction numbers of the algorithms are proved within a unifying framework to be bounded away from one, independent of the parameter and the mesth levels. Examples include the pure displacement and pure traction boundary value problems in planar linear elasticity, the Timoshenko beam problem, and the Reissner-Mindlin plate problem.
